There are many suitable raw materials for organic fertilizer. To choose the right compost raw materials, first of all, we need to understand the basic properties of various raw materials. In particular, some raw materials suitable for industrial and commercial production are suitable for the operation of organic fertilizer production equipment. Such as whether the sources are extensive and stable, whether the nutrient indicators of raw materials meet the requirements of fertilizer production, and whether the raw materials can quickly mature.
Raw material selection of organic fertilizer
The common raw materials of organic fertilizer include livestock manure, poultry manure, cattle manure, sheep manure, horse manure, crop straw and residue, cake, Chinese medicine residue, fly ash, bark sawdust and plane, peanut shell, wheat bran, etc.
NPK fertilizer production line does not need to ferment these processes, but when making organic fertilizer, the transportation distance of raw materials is a main factor to be considered. Generally speaking, the transportation distance of compost raw materials is not more than 100km, so organic fertilizer plants should try their best to find suitable organic fertilizer raw materials locally. Tianci fertilizer equipment manufacturers suggest that you divide it according to the amount of use, which can be divided into two types: main material and auxiliary material.
1. Main material
The main raw material is the main raw material for the production of organic fertilizer. Generally, this kind of raw material accounts for 30% - 80% of the material proportion. The main materials are generally composed of one or several raw materials. Commonly used are livestock manure, municipal sludge and peat.
Auxiliary materials are mainly used to adjust the water content, C / N, pH value and permeability of materials. They consist of one or more raw materials. In general, the proportion of such raw materials is not more than 40% of the whole material, and the proportion of single material is not more than 20%. Common auxiliary materials include rice straw powder, rice husk powder, rice bran, wheat bran, cake, mushroom residue, fly ash, quicklime, superphosphate, phosphate rock powder, etc.
The raw material composition is different and the ratio is different. When you want to make them into organic fertilizer granules, you must consider the appropriate fertilizer granulator.
